Only home custom built! Hubby builds them - only AMD motherboards usually 1.8Gigs. Pretty much what DJFyrewolf36 said. He can put together a 2Gig AMD system for about $300 that costs $800-$900 in the stores just by shopping around. We stay about a year behind the top of the line. The dealers all know him and so he gets good prices plus shops internet and eBay. No name brands and he won't touch anything Compaq. (proprietary and hard to work on) I doubt that we would ever buy a ready made brand name system because you can get so much more quality by going custom made. Also - the computers he builds come with tech support! Him for hardware and me for software and tutoring We only do it for family and senior citizens though.
